The ADG1201 is a monolithic complementary metal-oxide semiconductor (CMOS) device containing a single-pole, single-throw (SPST) switch designed in an iCMOS® process. iCMOS is a modular manufacturing process combining a high voltage CMOS and bipolar technologies. iCMOS enables the development of a wide range of high performance analog ICs capable of 33 V operation in a footprint that no previous generation of high voltage devices has been able to achieve. Unlike analog ICs using conventional CMOS processes, iCMOS components can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduced package size.
The ultralow capacitance and charge injection of this switch makes it an ideal solution for data acquisition and sample-and-hold applications, where low glitch and fast settling are required. Fast switching speed coupled with high signal bandwidth also makes the device suitable for video signal switching.
iCMOS construction ensures ultra low power dissipation, making the device ideally suited for portable and batterypowered instruments.
The ADG1201 contains a SPST switch. Figure 1 shows that with a logic input of 1, the switch of the ADG1201 is closed. The switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked.

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The EVAL-6SOT23EBZ evaluation board evaluates 6-lead SOT-23 devices in the Switches and Multiplexers Portfolio that are purchased separately. A clamp is supplied with the EVAL-6SOT23EBZ to secure a 6-lead SOT-23 device to the evaluation board without the need for soldering, making the board reusable for multiple devices.
A device can be clamped or soldered to the center of the evaluation board. Each pin of the device has a corresponding link from K1 to K6 that can be set to either VDD or GND. A wire screw terminal supplies VDD and GND. SMB connectors on the board allow additional external signals to be supplied to the device. In addition, there is space available at the top of the board for prototyping.
Full specifications of the device under test (DUT) are available in the corresponding product data sheet, which should be consulted in conjunction with user guide UG- 948 when using the evaluation board.
Features & Benefits
- 6 lead SOT-23 evaluation board
- Clamp to allow the main device to be changed easily
- Gold pin connectors to allow the addition of passive components
- SMB connectors for the input/output of signals
- Additional space on board to allow for prototypin
